peritoneal dialysis catheter
A peritoneal dialysis catheter is a flexible tube designed for peritoneal dialysis, the most well-known and widely-used being the Tenckhoff catheter.
In 1968 an American nephrologist Henry A Tenckhoff (d.2017) introduced his eponymous peritoneal indwelling catheter . The major improvements made by Dr Tenckhoff over the Palmer-Quinton catheter, the main one in use at the time, was:
- using the recently discovered inert and flexible Silastic as the catheter material
- the addition of Dacron cuffs near the ends to improve skin anchorage and decrease secondary infection rates
- developing and patenting an insertion trocar
